Two brothers, $20K, and $1.8B on the way
Matthew Gallagher built Medvi to $401M in year one using AI tools and no employees. Now tracking $1.8B with just his brother.

Matthew Gallagher launched Medvi — a telehealth platform for GLP-1 weight-loss drugs — out of his LA home with $20,000 and over a dozen AI tools. No team. AI wrote the code, generated ad creatives, handled customer service, and produced copy. First full year: $401M in revenue.
His only hire was his brother Elliot. That's it. Two people. This year they're tracking $1.8 billion.
The playbook is brutally simple: build an audience first, vibe-code a product for that audience, automate fulfillment with AI agents. No VC pitch deck, no hiring sprint, no burn rate drama. Sam Altman predicted the one-person billion-dollar company — Gallagher is basically the two-person version, already here.
Why it matters: the marginal cost of a startup just collapsed — the new moat isn't capital or headcount, it's how fast you can ship and automate.
